1. [Amps] Dummy Load (score: 1): Author: "Bob Maser" <bmaser@tampabay.rr.com>; Date: Mon, 14 Mar 2005 23:45:08 -0500; Anyone have a high power dummy load that would be willing to part with? I need at least 1KW, preferably more. Please respond off line. Bob W6TR bmaser@tampabay.rr.com ________________________________; /archives//html/Amps/2005-03/msg00331.html (6,133 bytes)

[Amps] Dummy Load (score: 1): Author: "Stefan" <ea5fy@ure.es>; Date: Mon, 23 May 2005 17:22:19 +0200; Dear friends I am trying to build a Dummy load made out of many parallel resistors (200x 10k/2W), and I am thinking of which would be the best configuration. I have seen (and even used myself) a bus; /archives//html/Amps/2005-05/msg00269.html (7,539 bytes)

I'm looking at a possible 50R 40dB attenuator based on the new thick-film-on-steel planar resistors by TT-electronics/Welwyn.

The inductance for 2-8KW is <3 uH and 5-16KW is <5 uH. Would be interesting to see some practical tests on HF. 73 B; /archives//html/Amps/2005-05/msg00286.html (10,319 bytes)

For example, you can easily make a 30dB T-pad using an existing 50 ohm dum; /archives//html/Amps/2005-05/msg00297.html (9,328 bytes)

Other resistors, for a 30dB T then, are Vishay parts, 47R 500W (FEC 306-8043), then 3R3 to deck, three 50W 10R in paralle; /archives//html/Amps/2005-05/msg00300.html (7,380 bytes)
